I have a digital output on an XA2 (MD4-7 controller) that showed orange in IQAN Design 4.07.7.4605 and indicated open load. This was good to me as I was troubleshooting some odd problems. I added some functionality to the project basically saying if I am commanding the output but it is not true shut my machine down. The problem is once I did this I disconnected the solenoid (unplugged din connector with built in led) to test my logic and it didn't show open load as I thought it would. with the din connector disconnected I cycled power to my MD4 multiple time and tried to recreate "open load" again and could not. I checked all wiring and the coil resistance and everything looks good. 

I also am not getting an intermittent no contact on that particular XA2 module which I was not getting before the program update. This particular program has 5 XA2's. Also the system ran for about 600 hours with out issues. 

Any ideas would be a great help. 

Hi,

It looks like there is no direct way to add digital out (HS+LS) on MC43. The only way I figure out was add a digital out (HS) and then change it to HS+LS. And sometimes, they are grey out.

Hi Guys,

I am using the "J1939 frame output" for broadcasting some messages and would like them Send Method "On request" How do I set what the request is?

Hi Guys,

Newbie here, was CodeSys, now starting IQan.

I have a project where I have two values (Two 5v sensors) operating all the time and I want to send the value of these over can on the same SPN etc but the one to send is requested by another SPN.

So I have sensor A and sensor B. Both use the same SPN 2927.

When SPN 3928 received equals 1, Sensor A value is sent on SPN 2927. When SPN 3928 equals 2, Sensor B value is sent on SPN 2927.

What do I use to set which value is be sent on receiving the SPN?

Cheers,

I am curious if SV cameras can be used on a multi-master application, where it could be wired into ethernet port on an MC43 and shown on a MD4 ?  

This would be a multi master system with master and diagnostic busses between MC43 and MD4.

Building a project with an MC43. 

In design 5, it seems that the limit for a COUT is 2000 mA.

In design 4, i can set it up to 2500 mA.   

1.  is there something that I'm missing  for setting it up to 2500? 

2.  is there any way to 'parallel wire' and run multiple COUTs? 

Thanks

Hi Guys,

All new to IQAN so sorry for the simple questions but have to start some where.

I am doing a project where some options are to be stored either true or false.

The message comes via CAN J1939 and then an SPN. So I have two options, both on two different SPN's and I want them to be memorized and stored where when one is received as true (01) then the opposing option memorized will go false. There wont be a part when both SPN's are received as true

 (01).

I simply added the two memorizing channels to the look at the SPN's and set to "STORE". the "Reset Value" was the opposing memorize channel. But nothing works?

In DOUT there are two functions.

One is Delay on [ms] or Delay off [ms] & the other is Soft Start time [ms] or Soft stop time[ms].

what is the physical effect of Soft start or Stop when we are operating a relay. As per our understanding it will ON or OFF when it reaches the required voltage. So it may be usable for some other load but for any relay or solenoids has it any effect?

Ability to adjust FP via MD3 buttons or MD4 VDIN without accessing FP adjustment screen.  

Hi guys,

I have been working with IQAN MD4s for a little bit now and I am curious if there are any developments in making push buttons for the MD4? I typically use industrial type HMIs but we have been starting to use the MD4 for the environment aspect. In a particular application I am working on now, it requires the HMI to have some push buttons for the operator to have some control through the screen. It would be nice to have a few options of pre-installed buttons so I can assign some internal digital registers. 

What I had to do to get around this was create my own bitmap buttons, import them in as images, create virtual digital inputs, and use the custom button with my made images to act as a button. It was a little cumbersome and tedious so I thought that would be something really helpful to implement into a rev of IQAN 5. 

Hope this is an idea that will be considered. 

Thanks!
